Fluid supply device, printing device, and method of controlling a fluid supply device

摘要

A fluid supply device, a printing device, and a control method for a fluid supply device can desirably supply a fluid while maintaining good throughput, and can reduce device size and cost with a simple construction. The inkjet printer 1 has an expansion mechanism that enables an ink refill operation in which a movable member expands an ink chamber by moving a piston that moves in contact with a regulator panel disposed to the main device side and supplies ink from an ink cartridge, a comparison means 113 that determines whether or not the amount of ink left in the ink cartridge 17 is less than a specified value, and a CPU 115 that sets a long time mode in which the ink refill operation time is long when the amount of ink left in the ink cartridge is less than the specified value.
